摘　　要：因瓦基线尺是国家野外大长度量值传递的法定标准器,本文通过对一组因瓦基线尺多年的检定资料、基线场的多次测量成果以及与维塞拉光波干涉仪测量成果的比较分析,论述我国野外大长度量值传递的稳定性与可靠性。The invar baseline wire is the statutory measure tool used for long distance length transfer in the field. The paper comparatively analyzed the measurement results from a group of test data of invar baseline wire for many years, the baseline field measure- ments as well as measurements from VaisaLa laser interferometer. It discussed about the stability and reliability of the long distance length transfer in the field.
